' WlRE-STAPLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 665,946, dated January1 5, 1901.

Application filed March 28," 1898. 7 Serial No. 675,496. (No model.)

To ttZZ whom it may concern:

Be it known that I, HENRY WEBER, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Wire Stitching and StaplingMachines, of

which the following is a specification.

This invention relates to improvements in wire stitching and staplingmachines in which wire intermittently fed into machines by suit: abledevices is cut off into suitable lengths, formed into staples, driventhrough the paper which itis desired to stitch, and clenched upon theother side of the machine, and particularly to improvements in the wirestitching and stapling machine shown and described in Letters Patent tome, No. 548,681, of October 29, 1895.

One of the objects of this invention is to provide an automaticmechanism by which the paper which is to be stitched may be held downand kept in place during the act of driving the staple through thepaper, it being frequently the case with old machines that, particularlywhen the pile of sheets through which the staple is driven is ofconsiderable thickness, the sheetsslip and become displaced, so that thestitching is not evenly and properly done.

7 in certain details hereinafter pointed out.

In the drawings, Figure 1 is a vertical section of the machine. Fig. 2is an enlarged detail, being a front elevation of the upper part of themachine carrying the cutting, staple forming, and driving mechanism andshowing, partly in dotted lines, the device for holding the paper inposition and the means for operating the same and also a portion of thetable on which the work rests. Fig. 3 is an enlarged detail,being avertical section made by a plane passing through lines 3 3 of Fig. 2.Fig. 4 is an enlarged detail, being a horizontal cross-section made by aplane passing through line 4 4 of Fig. 3. Fig. 5 is an enlarged detail,being a view of the. rear of a portion of the face-plate and showing thestaple-supporter seen from the rear. Fig. 6 is an enlarged detail, beinga front view of the staple-former. Fig. 7 is an enlarged detail, being afront view of the driver. Fig. 7 is a detail showing the clenchers.

In the drawings, 8 indicates the support-- ing-standard of the machine,upon which the several parts are mounted and carried. 9 indicates adriving-pulley driven in any appropriate manner and keyed or otherwisesecured to the shaft 10, which is journaled in the standard 8.

11 indicates a cam keyed or otherwise suitably seoured to the shaft 10.

12 indicates a rod slidingly mounted in the standard 8, so as to movelongitudinally therein.

13' indicates a roller journaled in the upper end of the. rod 12.

14. indicates a lever pivoted in the standard 8 and having upon itsinner end a slot 15, which engages with a pin 16 upon the lower end ofthe rod 12.

17 indicates a socket having a hole 18 and pivotally mounted upon theouter end of the lever 14.

19 indicates a rod, the lower end of which is adapted to easily enterthe hole 18 of the socket 1'7.

20 indicates a set-screw which is threaded in the socket 17 and operateswhen screwed in to firmly hold the rod 19 in the socket 17.

21 indicates a sliding block which is secured to the upper end of therod 19.

22 indicates clenchers of the well-known typesuch as are shown, forinstance, in said Letters Patent to me, No. 548,68l-a nd operate betweenjaws 23, actuated by connection with the sliding block 21 in thewellknown manner described by me in said Letters Patent No. $28,681 andwhose structure and. operation it is therefore unnecessary to describehere more fully than to say that when the set-screw 20 is screwed home,thereby firmly holding the rod 19 in the socket 17, the lever 14 beingoscillated by the bearing .of the cam ll upon the pulley 13,theclenchers 22 operate in the well-known manner described in said LettersPatent No. 548,681 to clench the wire. When it is desired to throw saidclenchers out of operation, the screw is loosened, permitting the rod 19to slide freely in the hole 18 of the socket 17, the hole 18 being madeof suflicient depth for the purpose. is relaxed,'so that the rod 19slides freely in said hole 18, all the rest of the machine may i beoperated'without the clenchers being operated, inasmuch as the socket'17 will move freely up and down over the'lower end of the rod 19without moving the same.

24indicates the back plate of the machine. 25 indicates a cam having acam-groove 26.

27 indicates a lever pivoted to the back plate 24 and having upon itsupper end a .former 30 at the back and operating in the cam-groove 26 ofthe cam 25. The lower end of the staple-former 31 is provided with twolegs of the usual form, as is best shown in Fig. 6, and is recessed inits face to slidingly carry a driver 33, which ismounted therein withtongues and grooves, as is best shown in Figs. 4, 6, and 7, in the usualmanner. I

The staple-former 30 is provided with ashoulder 34, extending across itsfront face and projecting slightly outwardly,asis best shown in Figs. 3and 6. The driver 33 is operated by a link 35, pivotally connected withthe upper end of said driver and with the surface of the cam 25. f

36 indicates an anvil having its upper surface beveled, as is best shownin Fig. 3, and

is provided in its front face witha slot 37, adapted to.receive thewire. The anvil 36 is slidingly mounted in the back plate 24 and support31.

38 indicates a tube which is rigidly secured to the back of the backplate 24 and surrounds the outer end of the anvil 36.

39 indicates a coil-spring which surrounds the anvil 36 in the tube 38and bears upon a shoulder in the outer end of said tube and.

upon a shoulder 40 upon the anvil 36 in such a way as to tend to holdthe anvil 36 forward in the position shown in Fig. 3.

, The movements and operation of the stapleformer,driver 33, and anvil36 in formingan-d driving the staple are of the well 5 knowncharacter,as described in my said Letters Patent No. 548,681, and neednot be further described here. Y

41 indicates a staple supporter which is It is obvious that when thescrew 20 curved upon itslowersnrface,as is best Shown in Fig. 3, isprovided with a beveled surface 42, and its upper end with a slot 43.

44 indicates a pin which passes through the face-plate 45 and the slot43 of the supporter 41, so that the saidsupporter may move freely up anddown upon said pin to the extent of the length of the slot 43 and mayalso swing .upon said pin, the face-plate 45 being suitably recessed tosupport ,the said wire-supporter and cut away in front to permit theswinging of the said supporter, as is best shown in Figs. 3, 4, and 5.-I

46 indicates a pin provided with a shoulder 47 and slidi-n'gly mountedin a tube 48, which is secured to the face-plate 45.

49 indicates a'spring bearing upon a suitable shoulder of the tube 48and upon the shoulder 4'7 of the pin 46- and operating to force thestaple-supporter 41 to the right in Fig. 3 when not forced to the leftby the operation of the d riverupon its beveled surface 42, hereinafterdescribed.

The staple-supporter 41 is provided with a shoulder 50,adaptedto engagewith the shoulder 34 of the staple-former 30.

The operationof these devices is as follows:

Wire being fed into the machine in appropriate lengths by anyappropriatefeeding mechanism-such, for instance, as that described in said LettersPatent to me-and severed by any suitable cutting mechanism,

such as that described in said Letters Patent,

the severed portion of the wire to form the staple rests in the slot 37of the anvil 36. The staple-former being driven downward at the propertime in the manner described by said patent bends the wire upon eachside of the anvil downward, forming the legs of the staple. The driver33, coming into operation, first meets with the beveled surface of theanvil 36, forcing the same backward, allowingthe staple formed by thestaple-former to rest upon the beveled surface 42 of the supporter 41..In the meanwhile by the descent of the staple-former 30 the shoulder 34is lowered, so as to free it from contact with the shoulder 50, thusallowing the staple-supporter 41 to drop and rest upon the surface ofthe pile of paper below it. At this time the driver 33 descending, itslowerend comes in contact with the horizontal portion of the stapleresting upon the beveled surface 42 IIO and bearing upon said beveledsurface forces a clenched by the clenchers 23 in the'well-known mannerdescribed by me in the said Letters Patent No. 548,681. As the driver 33is retracted the staple-supporter 41 is swung inward by the operation ofthe spring 4:9, and the staple-former 30, raising the shoulder 34, comesin contact with the shoulder 50 of the staple-supporter 41, lifting thesame into the position shown in 3 in unbroken lines. Fig. 3 shows indotted lines the position of the staple-former when allowed to drop soas to rest upon the paper. I

51 indicates the table upon which the paper rests and which may be ofany approved form and construction-such, for instance, as that describedby me in said Letters Patent No. 548,681.

52 indicates a presser which is provided with slots 53, through whichpass screws 54 in the back plate 24, so that said presser 52 isvertically movable thereon. The lower portion of the presser 52 isprovided with bifurcated arms 55, which are bent forward at right anglesand extend toward the front of the machine upon each side of thestaple-supporter 41, as is best shown in Figs. 2 and 3.

56 indicates a rock-shaft journaled in the plate 24 and provided withtwo arms 57 and 58. The free end of the arm 58 engages with a suitablerecess 59 in the presser 52, as is best shown in Fig. 2.

60 indicates a link which is pivotally connected at one end with the arm57 and is provided at the other with a slot 61, through which passes apin 62 in the lower arm of the lever 27, so that said pin 62 may slidewithin slot 61. As the lower arm of the lever 27 is swung to the rightin Fig. 2 by the operation of the cam 25 upon the roller 28the pin 62,meeting the end of the slot 61, urges the link 60 to the right, thusrotating the rockshaft 5b and throwing the arm 58 downward, which alsothrows downward the presser 52, so that the bifurcated arms 55 rest uponthe surface of the paper and hold it firmly in place upon the table 51.The movements of the parts are so timed that the bifurcated arms 55shall rest upon the paper and hold it in place before the driver 33operates to drive the staple into the paper.

63 indicates a retractile spring, one end of which isfastened to theback plate and the other to the arm 58. As soon as the lever 27 beginsits backward motion, being freed from the operation of the cam 25, theretractile spring 63 operates to raise the arm 58 and lift the presser52 from the surface of the paper, the driver 33 having in the meanwhileoperated to drive the staple into the paper.
